We don't know whether 737 Max MCAS update is coming or Boeing: Anti-stall safety fix delayed

Re: I'd fly in one today.

"a properly trained pilot at the controls"

THIS is the problem. The MAX was sold with the promise that existing 737 simulators could be used to qualify pilots for the new airframe. Given that special training is actually NECESSARY for the MCAS feature, the correct fix will probably include fixing the simulators, too...

Aggressive marketing campaign drives development into a direction it probably should NOT have gone. "Agile" perhaps?

Re: Whoopsie

the smelly stuff added to natural gas has more than just H2S in it but is a cocktail designed to be easily smelt, uniquely enough that people immediately think of natural gas leaks when it's smelled.

But yeah, smelly stuff added to CH4 to make it detectable by smell.

I think Methane Thiol [a 'poo stench'] is also in there. https://en.wikipedia.org/wiki/Methanethiol

But yeah pretty much any gaseous material containing sulphur is gonna stink.

Re: Don't travel to the US.

I have an idea:

a) fed-ex all "real" devices to/from your destination endpoints

b) carry only what you need to have on a 'burn device'.

It's not hard (in most cases) to create a gmail (or other) mail address, then forward everything to it while you're away, and fix it back when you return.

And other than listening to music or watching movies on a plane [SD cards good for this], a smart phone isn't all that necessary.

Avoid the problem entirely by making yourself a VERY small "digital target".

Or you can have FUN with them by doing something like this:

1. use FreeBSD on your laptop

2. create a jail that TSA can log into. Make sure the passwords are pejorative towards them.

3. Make it log into a console, not a GUI, and pressing any ALT+F-key gets you a virtual console into the jail [I know how, I have done this, and it's not that difficult]. You can still SSH into the host from the jail...

4. When TSA has you power it up, he sees a classic login prompt on a text console. When he asks for user+password, give him the one that's pejorative to TSA. "What, that's my password!"

5. If they want 'root' password too, give them THAT one. A FreeBSD jail has a different security context, so root's password is not the same as the host's. Make THAT one pejorative towards them as well, or a profane term, or something similar.

Anyway, you give them what they want, just like they ask, and they shouldn't complain, but you're also protesting and pissing them off. Smile the entire time.

Re: Don't travel to the US.

ACK. These are tactics of FASCISTS. Not the other way around. Think 'brown shirts'. Who wants to live in an environment like THAT? The people making the accusations, it seems, are even guiltier of the SAME THING.

Getting closer to easter, there's this bible passage I know about. Apparently Jesus said it, something about removing the log from your own eye before removing the speck of sawdust from the other guy's eye. This is SO typical of hypocrites, to be guilty of doing something (say intolerance), then IMMEDIATELY spot "intolerance" in others they disagree with, and be all righteously indignant about it, getting on their soapbox and using every '-phobe' and '-ist' term they can recite, call for firings, picket people's houses, harass people in public, etc. - all while simultaneously being GUILTY of the SAME DAMN THING.

Re: "Voicing their opinions" and other fairy stories

"Fascism is all about totalitarian control."

Definition of fascism: a militant form of socialism that does government takeover of nearly all industry.

It's a form of totalitarianism, yeah.

Communism in its worst form is very much like it, except that ownership has been removed and substituted with a rude form of 'collectivism', managed by an 'elite' group of 'leaders'.

In both cases, a small oligarchy benefits, while the masses suffer under the thumb of mediocrity.

Funny how fascism and communism must be FORCED upon the masses, whereas freedom has a life of its own and typically "finds a way". It's human nature to be free. It's AGAINST human nature to be SOCIALIST or COMMUNIST.

But yeah, that was the last time I did anything with 2.4, on wifi routers, 10+ years ago.

NASA 'nauts do what flagship smartphone fans can only dream of: Change the batteries

Re: Replaceable batteries.

the thing about LiPo and LiIon batteries is that they tend to wear out faster than NiMH (from my experience, anyway) although their weight is significantly lower.

That, and the tendency to catch on fire if you don't treat them right.

(Being surrounded by a vacuum might make LiPo/LiIon safer, though)

Lithium, next to hydrogen, is the most reactive material, and is the most reactive metal. And lithium batteries have a charge/discharge behavior curve that you need to be very careful with. Over-discharge them and they start outgassing, which greatly reduces their performance and life expectancy.

And for some reason, I never seem to get a typical LiPo or LiIon to last NEARLY as long as an NiMH battery can last. Laptop batteries in particular seem to fail more readily when they're lithium based, but I still have old NiMH batteries for old laptops that work just fine, even 15 year old batteries (with reduction in capacity, but still holding a charge). Go fig, yeah.

(worthy of note, I was deeply involved with charge cycles on a LiPo battery for a customer project a short while back, from charging circuits to undervolt protection and why I needed to design that in)

Anyway, lithium batteries are a bit overrated in that regard. But as it's only for another, maybe 5 or 6 years, I can see (because of weight alone) why NASA would swap in lithium batteries for NiMH.

Re: blocker

sort of blocker: a plugin (like the 'cookie white list with buttons' plugin for firefox) that allows you to accept all cookies but put non-white-listed ones into memory only, not on disk. Then when you turn off cookie acceptance (and maybe right back on again), or close the browser, they go into the bit bucket.

bombastic bob Silver badge
Devil

Re: Let's report every case of this to the ICO

For Firefox, there's a plugin (or was, I'm using version 56 still) of 'cookie white list with buttons' or similar title. In short, you can tell it to accept ALL cookies, as long as the button enables cookies. But only whitelisted cookies are stored on the hard drive. The rest go into 'write only memory' when you disable cookies or close the browser. Dumping all cookies is basically "turn it off, turn it back on again" [except for whilte-listed cookies, of course]. So it doesn't SOLVE the problem, but it sure keeps it under control.

In fact, if this were a standard browser feature (HINT HINT) to ONLY store non-white-list cookies IN MEMORY, and give users the ability to "dump all" or shut off their acceptance with a button or a menu option, it might actually solve 99% of the cookie tracking problems. In many cases you'd get those irritating "someone logged on to your account" e-mails but so what. The entire point is to eliminate the tracking, and flushing cookies periodically (yes, obvious reference to "the loo") would really screw them up. And what would happen if EVERYODY did it? they'd have to do something ELSE.

and 'tick boxes' on a permissions page would no longer matter. And, maybe the browser/plugin could prompt you with "do you want to store this cookie permanently" (with the options to block it [black list] or keep it in memory until you flush/exit [normal handling]) so you can see what they're up to and have some additional choice.

Re: Enterprise apps? We've heard of them.

"I guess you can still install apps from outside the playstore which can access these features"

Yes, and in some ways the 'new method' (individual approval of each application NOT certified by 'Google Play') is better than the old one (wildcard enabling of any application install from outside of 'Google Play') though I have had to jump through hoops a bit to get it to work so far.

But this might not be possible if the Android OS is updated to simply exclude ANYTHING that wants access to 'certain features' (from permission flags in the 'manifesto' let's say, similar to now) when those feature requests are on 'a list' and there's no cert or other 'permission mark' from the Play store's signage info to allow it....

I also don't know what affect this will have on any legacy home-brewed and locally signed APKs, which [for now] can be made available via a web page or be directly copied into the Android's file system via USB. Enterprise applications needing access "to everything" might STILL be possible, doing it this way. (edit: someone else calls this 'side loading' I guess; not a term I'd used before, might have seen it, didn't stick)

Google is (wishful thinking?) *trying* to protect end-users from themselves, without becoming TOO much like Apple with _THEIR_ store (bans because "Apple just don't like it"). Well, I hope so. And apparently it's a reaction to rogue applications. No surprise, but little excuse for THIS kind of "solution".

Google could offer a better method, using something similar to 'Firebase' for authorization keys (let's say) that are verified at install time from the Google Play store. That's not ideal, but at least it would help to control the "rogue" behavior by adding some extra 'permission steps' and not outright BANNING functionality.

And, it COULD get worse... they could become 'Apple'. Or even MORE like them.

Re: Why on earth would Google have a problem with BlackBerry Hub?

I think Google is becoming more like Apple with their store. But as long as I can install "any APK" so long as I enable that on the device, it's less of a problem. It's just that the user will be prompted with a "scare message" during the install.

Android's sandbox for user applications is a bit irritating, more so NOW. A more 'open' platform would be much easier to work with, but then would expose users to being duped and spied upon. However, when you have to go through the list of applications on someone's phone (friend, relative, BYOD) and specifically DENY access to the phone's location (or in this case, SMS and call logs) for a GAME or ART application, which has NOTHING to do with the capability they claim to "need", then it's kind of obvious why Google did this.

I don't like it because it sets a precedent, requires "permission" to do what you've been doing all along, etc.. I thought the 'permissions' stuff in the 'manifesto' was supposed to take care of this, make sure the end-user knows what the application is trying to, etc. but apparently NOT any more...
